We’re being asked tocalculate the mass of water will be formed when 32 grams of hydrogen and 32 grams of oxygen are mixed and allowed to react:
2 H2 + O2 → 2 H2O (the reaction is balanced)
Notice that we are given the mass of both reactants: this means we need to determine the limiting reactant. To determine thelimiting reactant, we need to determine which is the reactant that forms the less amount of product.
You are watching: 4 grams of hydrogen and 32 grams of oxygen will combine to form
This is because once the limiting reactant is all used up, the reaction can no longer proceed and make more products.This means the limiting reactant determines themaximum mass of the product (H2O) formed.
